Each positive plete lgfrovidedV :it one siffle with the usual upwardly extending lng b, and each negative pla-te has n iinihir lug n, the lugs of the posi-tive plates being loczitted :it one Side ot the cell find joined hy :L connceilingi strip or liar b, while theA lugs ot lll-ie` negative plates ure. located :it the op posite Side ot' the cell :nid joined by :L sinii lor connecting strip or bnr 0"., 'these conf- 'necting strips are arranged within the jen?,

to permit ai close arrangement of the seveiribpells of e. battery. and .firefpiieferably zirrfiiged on edge or with their Smallest dimension horizontally.I to permit the use of Strips of the required Sifey while occupying The battery plates are narrower than the in teruel diameter ordiinension oli the jar and :ire arrmiged in Stnggercd order, that is, Lhe upright edges ot' the. )iositive plates, `which :tref joined by the connecting har b." extend toward the wall' of the jose lieyoud the adjacent side edges ot the negative plates, while the oppo ite side edges of the negar tive plates. which :irc joined by the connecting limi c', similarly project beyond the :uljzicent edges ot the pmitive plates. The plates of each set terminate at :i sollicitent distance from that side ot the jim' :it which the connecting strip. tor the other set of plates is located. to enable either set of platee to: loe lifted vertically ont ov the -l'ORAGE BATTERY WithoutL disturbing either set of plates. rIhe staggered arrangement of the plates also permits the use of larger plates, giving greater surface area, than would otherwise be possible in an arrangementpermitting the independent removal of the sets of battery plates and the separators. Any one or all of the separators can be removed, cleaned and returned Without disturbing the plates in the cell or the 'connections between the plates of differentcells.

E represents the usual insulated supports at the bottom of the jar for holding the plates above the bottom to provide a space I beneath the plates for sediment and detached particles of the active material. in order to hold the plates and separators in the stated relation the bottom edges of the plates and separators are notched at c and f, respectively, to 'engage these supports. .The up er ends of the separators-(are also prefera ly held from relative movement by some suitable means, that shown consisting of a hollow rectangular piece or frame G of insulating material arranged on edge upon the separators and seated sin notches in their upper edges which are located above the upper edges of the battery plates.` The retaining piece G serves as a support for the usual cover plate H for the jar end is held from shifting by depending lugs L on the cover plate or other means.

The cover plate H is situated between the upwardly projecting logs b and c gf the positive and negative plates, being thereby held from shifting horizontally and at the same time acting to hold the one set of plates from lateral movement independently of the other. All of the parts are thus held from movement relative t0 each other and, owing to their combined Weight, especially wheny the plates of diferent cells are connected, there is little liability oi the movement of the .parts in the jar. The outer faces of the connecting strips b c, see Fig. l, are beveled` at z' so as to diverge upwardly from the walls of the jar, and tnhereby allord suflicient space between the walls of the jar and the connecting strips and the connectors t" ris` ing therefrom to prevent capillary action and the consequent wasting of the electrolyte. As the battery plates rest on the suports E the connectors i need nel? beer on p v the top edges ofthe jar and, as shown, are

spaced therefrom" to further preventI capih laryfaction between the same andfilie walls or the jar.

The devices described for holdin the plates and separators in position are clicient and desirable, but any other suitable instrumentalities may be employed lor this purpose.

l claim as my invention:-

l. In a storage battery cell, the combination of a containing vessel, a set of. positive plates and a set of negative plates, each connectedfb'y atransverse bar which is arranged within the cell and laterally beyond the adjacent upright edges ot the plates of the opposing set, and separator plates'intcrposcd between opposing plates and of less width tlmnthe distance between the bars, whereby each set of plates can be raised from the vessel without disturbing the opposing set and each separator plate can be removed Without disturbing the battery plates, substantially as set forth.

2. ln a storage battery cell, the combination of a containing vessel, a set of positive plates and a set of negative plates, each connected by a transverse bar which is arranged within the cell and laterally beyond the adjacent upright edges of the plates of 'the opposing set, the plates of eachsct being of greater width than the distance between said connecting bars, and separators interposed between the opposing plates, said separators being of width than the distance between said bars and disconnected from said plates, whereby each set of pluies can be raiscd from the vessel without disturbing the opposing scf and each separator can be removed without disturbing said plates, substantially :is set t'orth.
